Unmanaged switch TP-Link TL-SG105-M2 5-port 2.5G desktop-switch

The TP-Link TL-SG105-M2 is an unmanaged 5-port 2.5G desktop switch that delivers multi-gigabit connectivity for home and small office networks. With five 2.5G RJ‑45 ports supporting auto-negotiation at 100 Mb/1G/2.5G and a switching capacity of 25 Gbps, it enables higher throughput for devices such as 2.5G NAS, 2.5G PCIe adapters, WiFi 6 access points, gaming consoles and desktop computers. The fanless metal design supports quiet operation on a desktop or mounted on a wall and requires no configuration — simply plug and play.

Advantages

The switch provides 2.5× faster speeds over existing Cat5e cabling without requiring Cat6 upgrades, reducing installation cost and complexity. Its auto MDI/MDIX and three-speed auto-negotiation ensure broad device compatibility while a durable, fanless metal enclosure offers silent, reliable operation. With an unmanaged, plug-and-play design and IEEE networking standard compliance, the device is simple to deploy and maintain.

Suitable for

• Home and small office networks needing higher-than-gigabit uplinks
• Connecting 2.5G NAS or 2.5G PCIe network adapters
• Linking WiFi 6 access points for improved wireless backhaul
• Gaming setups and low-latency LAN parties
• Desktop workstations and 4K video streaming sources

How to use

Place the TL-SG105-M2 on a stable surface or mount it on a wall. Connect your router, access points, NAS, PCs or other devices to the 2.5G RJ‑45 ports using standard Cat5e or better Ethernet cables. The switch will automatically detect link speeds (100 Mb/1G/2.5G) and configure MDI/MDIX so no crossover cables or user configuration are required. Power the unit and confirm link/activity LEDs to verify connections.

Recommendations

For best results, use Cat5e or higher-rated cables and connect 2.5G-capable devices where possible to benefit from multi-gig bandwidth. Place the switch in a well-ventilated area despite the fanless design, and avoid covering the metal casing to ensure proper passive heat dissipation.
